"Could not detect a board" target hardware

Using a Lenovo laptop host machine running Ubuntu 18.04. I have a jetson nano 4gb with dc power and a blank 64gb SD card for storage.

I have a green light on the board when powered on but when I plug it in via micro USB the program does not detect the board so I cannot flash board.

Any help would be appreciated as I am not familiar with this device. I already tried flashing an image onto the sd card and that did not work which I why I have to flash the board.

Are you using Jetson Nano devkit or with other carrier board?

Jetson nano dev kit 4gb edition

Did you put the device into force recovery mode?
Was it detected with lsusb?

I’m not sure what that is. I’m sorry. Should I give that a try?

Force recovery mode is like the first thing you need to know when it comes to flashing a Jetson device.
Check this guide:

First make sure whether you are using the A02 or B01 revision, and follow the instructions accordingly:

[J40] Carrier board rev A02 only: 8-pin button header; brings out several system 
power, reset, and force recovery related signals (see the following diagram).

Pins 3 and 4 put the developer kit into Force Recovery Mode if they are 
connected when it is powered on
[J50] Carrier Board Rev B01 only: 12-pin button header; brings out system power, 
reset, UART console, and force recovery related signals:

Pins 9 and 10 put the developer kit into Force Recovery Mode if they are 
connected when it is powered on

Basically, you shorten the two pins with a jumper, and plug in the power cable to put the device in force recovery mode.

That seemed to work!!! Thank you! I was able to connect and get it up and running. Now I think I just need to follow the obico guide to get the AI running. I also need to get it to auto login and launch some select programs.

Thank you so much for your help. You are awesome!
